I just hooked up my ancient Epson 2450 to my new iMac. The software CD with the license keys for Silverfast is so old, the version I'm using on my PC would not be supported for the latest flavor of MacOS X (this is one of the new Intel macs). So, I downloaded the standard Epson drivers. Wow- what an improvement! The version they had for the PC was terrible, and had no decent controls - everything on it was automagic. Now, it does a terrific job, and gives you most of the controls you'd want from Silverfast AI. Still picks up the paper texture too much when scanning pt/pd prints, but that's life, I guess. I'm also just stunned at how crappy the image on the monitor was with my PC, and how much better the Mac is. Yay, wow! Now I just need to get the ICC profiles for my 2200 printer and I'll be in business!
